## Homework Statement

A 2.3kg aluminum pan at 135° is plunged into 3.0kg of water at 15°. The specific heat of aluminum is 900 J/(kg K).

Part A

Find the final Celsius temperature of the aluminum and water.

T_f = °Celsius

Part B

Find the entropy change of the aluminum pan.

ΔS_Al = J/K

Part C

Find the entropy change of the water.

ΔS_H20 = J/K

Part D

Find the entropy change in the system of particles consisting of all the particles in the aluminum plus all the particles in the water.

ΔS = J/K

## Homework Equations

Q=mCΔT

ΔS=Q/T

## The Attempt at a Solution

So my first couple attempts was that we use the equation Q=mC(T_f-T_i)

other related equations i know is DeltaS=Q/T but, how can i find the temperature final of both Water and aluminum.

I tried setting it up like this

m_water*C_water(T_f-T-i) + m_aluminum*C_aluminum(T_f-T_i) = Q_total

but i don't know how to get anything done from there.

Please help me with the first part and i should be able to most of it done on my own.
